Getting error while authenticating U2F token with com.yubico 0.18.1 about java-u2flib-server

Hi!

Looks like KeyFactory doesn't have access to a BouncyCastleProvider security provider. This should be set up by the static initializer in BouncyCastleCrypto, but I suspect that's a bit fragile.

Is this an existing system or a new one in development?

I pushed an attempt to fix this on branch issue-39-ecdsa-keyfactory-not-available, you're welcome to test if that works for you.

Thank you for this fix! Could you please tell me the version for u2flib-server-core version.
Currently we are using 0.18.1

I haven't released the prototype as a versioned release yet. Are you able to try to build branch issue-39-ecdsa-keyfactory-not-available and test if the fix works?

I have tested this with main method

public static void main(String[] args) throws Exception {
Provider provider = new BouncyCastleProvider();
Signature ecdsaSignature = Signature.getInstance("SHA256withECDSA", provider);

    X9ECParameters curve = SECNamedCurves.getByName("secp256r1");
    ECPoint point = null;

    KeyFactory.getInstance("ECDSA", provider).generatePublic(
            new ECPublicKeySpec(point,
                    new ECParameterSpec(
                            curve.getCurve(),
                            curve.getG(),
                            curve.getN(),
                            curve.getH())));
}

It is now working fine and its not throwing any exceptions

Requesting you to release this one!

Great, thanks! I just pushed version 0.19.3-RC1 into the relase pipeline, it should show up on Maven Central soon. If nothing else comes up in a week I'll promote it to a proper 0.19.3 release.
